Concept explainers
In 1937, Claude Shannon showed that computer scientists could use symbolic logic to design computer circuits by using the following approach. Electricity passes through a switch when it is closed and does not flow when the switch is open.
Open switch | Closed switch |
As shown in the following diagram, electricity flows through a series circuit only when switches p and q are both closed. A series circuit corresponds to a conjunction,
Series circuit | Parallel circuit |
We can build more complicated circuits by combining series and parallel circuits.
